In rare cases, the cornea may freeze, which can lead to
blurred vision, sensitivity to light, eyelid spasms (blepharospasm), excessive
tearing, and pain when you try to rewarm the eye.

Snow blindness
is not directly caused by cold temperatures but does occur in snow conditions.
Sunlight reflecting off the snow causes a corneal injury or
burn. Eyelids may become red and swell. The eyes may feel dry and as
though they have sand in them.

Treatment includes rewarming the eye and
medicine to moisten and protect the eyes.
